Shingo's Seven Wastes

Shingo's Seven Wastes: The seven ways that wastage can occur in industrial processes, put forward by Shigeo Shingo, an engineer at Toyota and a noted authority on just in time techniques. They are:

• waste of overproduction - make only what is needed now;

• waste of waiting;

• waste of transportation;

• waste of processing - does this product or part need to be made?;

• waste of stocks;

• waste of motion - first improve, then mechanize or automate;

• waste of making defective products - accept no defects and make no defects.
